Ann paid $5.20 in sales tax for an $80 purchase. What percent sales tax did Ann pay on her purchase?

6.5%

You can use proportion:

80 is 100%

5.20 is x %

80/5.20=100/x

80x=5.20*100

80x=520

x=6.5

So Ann paid 6.5% sales tax on her purchase.

answer. d.289 hope that

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
